\"exponents<\/p>\n

the basics of exponents<\/h2>\n

there are two parts to an exponent: the base and the value of the exponent itself. the base tells you what is being multiplied by itself, and the value of the exponent tells you how many times the base gets multiplied.<\/p>\n

for example, 54<\/sup> is equivalent to 5*5*5*5. the 5 is the base, and the 4 is the exponent. laid out like this, it is easy to see why exponents can be simplified. since we are combining large amounts of the same numbers being multiplied together, we can easily group them.<\/p>\n

most problems that have to do with exponents on the act test you on your ability to simplify correctly. therefore, it is vital that you know the rules on how to combine exponents in order to turn complicated expressions into something more manageable.<\/p>\n

with careful practice and repetition, you won’t have to rely on memorizing rules. instead, it’ll become almost second nature, allowing you to concentrate on deconstructing more difficult problems and concepts. <\/p>\n

how to tackle exponents on the act<\/h2>\n

dividing exponents with the same base<\/strong><\/p>\n

in order to divide two terms containing the same base, subtract the exponents and keep the base.<\/p>\n

for example, 35<\/sup> \u2013 33<\/sup> = 32<\/sup>.<\/p>\n

multiplying exponents with the same base<\/strong><\/p>\n

in order to multiply two terms containing the same base, add the exponents and keep the base.<\/p>\n

for example, 35<\/sup> + 33<\/sup> = 3<\/sup>8.<\/p>\n

raising exponents to a power<\/strong><\/p>\n

in order to raise an exponent to a power, multiply the exponents and keep the base.<\/p>\n

for example, (35<\/sup>)5<\/sup> = 325<\/sup>.<\/p>\n

evaluating negative exponents<\/strong><\/p>\n

in order to solve for negative exponents, take the reciprocal of the base and exponent. after that, change the sign of the exponent from negative to positive.<\/p>\n

for example, x-5<\/sup> = 1\/x5<\/sup>.<\/p>\n

evaluating fractional exponents<\/strong><\/p>\n

evaluate the numerator of the exponent like normal. evaluate the denominator of the exponent as you would a radical.<\/p>\n

for example, x(5\/2)<\/sup> = the square root of x5<\/sup>.<\/p>\n

squares and cubes<\/strong><\/p>\n

squaring a number means to multiply the value by itself. <\/p>\n

cubing a number is taking it to the third power.
